A friend of mine has a flat where the sole access is an external uncovered staircase which I can best describe as a fire escape with timber cladding to the bottom and sides to make it look a bit better. It's been in place for over 30 years, and is now extensively corroded to the point it has got past any localised repairs and needs total replacement.
Looking to get some quotes in from specialist fabricators, but has anyone ever had work of this type done and have any idea of the order of magnitude of the cost, and what sort of building regs are applicable? The staircase itself isn't complex nor does it need to be decorative - it's a straight run across the back of the building comprising two 16 step sections and a landing section to break them up.
TIA, Midge.
